QUEENS - New security changes are coming to U.S. airports to deal with a new type of bomb threat.
Some passengers on domestic flights will now have to power on their electronic devices, including cellphones and laptops, before flying. If the devices do not turn on, they will not be allowed on the plane. The new safety check is already being used on international flights coming to the U.S.
Federal officials say there is intelligence indicating terrorist groups are trying to perfect an explosive that could be hidden in electronics. The new bombs could also be made of plastic to evade detection by metal detectors.
Many travelers at LaGuardia Airport say the security measures may be inconvenient, but they are necessary to keep passengers safe.
